How to get rssi without connection via central device

[purgoufr]

I use nrf51822 sdk130 (central device) and nrf51822 sdk110(peripheral device). I want to get rssi value of the peripheral device using the central device without connection. Is it possible to read rssi value of peripheral device without connection?

Sure, each scanning event (when you receive ADV_xxx packet) has RSSI value in the event data structure.

Yes, this will start the scanning, now you just need to handle incoming events. Good luck!
